Definitions

  • the present invention relates to a scooter, preferably an electric scooter, provided with suspension means that implies a simpler arrangement, more steering possibilities, specially more reduced steering components.
  • the invention can also be applied to a mechanical scooter or to a tricycle having only one front wheel.
  • DE9403582U1 discloses a collapsible scooter having a footboard and a steering column.
  • the footboard is arranged on two tubes running parallel to each other.
  • the steering column is connected to a support member for the front wheel of the scooter.
  • the steering column is rotatably connected to the footboard by means of a steering head.
  • the scooter comprises a rod rotatably connected to the axis of the front wheel and to the two tubes. The rotatable connections render the scooter collapsible, decreasing the amount of space required when storing the scooter.
  • the suspension of the scooter can be further improved.
  • US5127488A discloses a power accessory that can be retrofitted to a skateboard.
  • the power accessory comprises a drive assembly comprising a combustion engine which powers a drive wheel.
  • the skater can control the power supplied to the drive wheel by means of a hand grip.
  • the hand grip is connected to the drive assembly through a cable.
  • the drive assembly is attached to the skateboard by means of a leaf spring.
  • the drive assembly is mounted on one end of the leaf spring and the other end of the leaf spring is attached between the rear truck and the body of the skateboard.
  • the leaf spring has a slight offset in it so that when the leaf spring is connected to the body of the skateboard, the rear wheel of the skateboard is off the ground when the skateboard is unloaded. When the skateboard is loaded, the leaf spring is deformed, making the rear wheel contact the ground.
  • An advantage of the power accessory is that the skateboard has the same steering characteristics after installation of the power accessory. However, a simple steering mechanism easier to operate is desirable.
  • a scooter having a board member on which a rider can stand.
  • the scooter has a vertical shaft attached at one end of the board member.
  • the vertical shaft is provided with a horizontal handle at the top thereof.
  • the aim of the handle is to improve balance of the rider and can be used to effectuate jumps and other aerial maneuvers.
  • the scooter comprises an arcuate leaf spring under the board member. The arcuate leaf spring is not attached to the board member but rather engages the board member when a downward force from the weight of the rider is applied.
  • GB151691A discloses a motor driven scooter which comprises a footboard and a front wheel carried by front wheel fork.
  • An up and down swingable member carries the front wheel fork and, at another section, the swingable member carries an active housing.
  • One end of a spring is fixed to the active housing while the other end of the spring is fixed to a stationary housing. In this way, swinging of the swingable member causes swinging of the active housing and hence the spring changes its curvature. In this way, the spring springs the front wheel of the motor driven scooter.
  • GB 156970 A , CN204296995U , EP3000704A1 , US2002109323A1 and US5154436A disclose scooters comprising a user support platform, a front wheel, a front fork of the front wheel, and suspension means of the front wheel, the suspension means comprising an impact absorber linked to the platform, the impact absorber being movable or deformable only in planes parallel to a median plane of the platform such that the front fork of the front wheel is rotatable with respect to the single leaf spring to allow steering of the scooter.
  • GB 156 970 A is considered the closest Prior Art and discloses the features of the preamble of claim 1.
  • a simple, small and compact steering mechanism easier to operate is desirable.
  • a scooter where it is decreased the degree to which the user feels bumps in the ground while driving the scooter.
  • the present invention proposes a scooter According to claim 1.
  • the median plane must be understood as a plane that divides the main body of the scooter into two equal parts, that is, it is a plane of symmetry of the scooter. It can also be defined as a plane containing the longitudinal direction of the scooter and a line perpendicular to the user's support platform. Another way of expressing it would be as a vertical plane that passes through the longitudinal direction when the scooter is in vertical arrangement. In any case, this medium plane has been represented in the figures to leave no doubt.
  • this plane is essential for the correct interpretation of the claimed subject matter.
  • the impact absorbing is deformable or movable in said plane, it means that its degrees of freedom of movement are contained in that plane and that it can also rotate or deform in that plane, which It should be understood that the vector describing its rotation or the vectors defining its deformation is/are a vectors perpendicular to its plane. In other words, all points of the impact absorber move in planes parallel to said median plane. It does not at all mean, as the skilled person knows, that the impact absorbed is contained in the mentioned plane.
  • this support is a fork.
  • the characteristics of the invention allow making dynamically independent, in a region as close as desired to the wheel axis, the damping and steering functions.
  • the invention allows the forces caused by the impacts to be brought along the shortest path to the platform and, on the other hand, allows the structural requirements of the steering elements to be drastically reduced.
  • the suspension means are integral with the steering bar. That implies that the steering bar carries with it the suspension elements, which in most cases involve a large mass that is rotatable with the steering bar itself.
  • the steering means are complex and forces the driving means, i.e. the user, to deal with the inertia of the suspension and damping components.
  • the fact that the suspension elements rotate together with the wheel imply limitations in the design of its components, which involve both the elastic recovery element k and the damping c.
  • Another drawback that is overcome is the complexity, and hence the lack of aesthetics of the prior art solutions.
  • the present invention by separating the functions, open a great variety of possibilities both for the steering of the wheel and for the suspension means.
  • the only limitation involved in the present invention is guaranteeing that the rotation of the front wheel support has the minimum friction with the impact absorber.
  • the main relative moment therebetween is the steering rotation movement, which can easily be dealt with bearings, which, considering the forces involved, can have a very reduced dimension.
  • the impact absorber is a single leaf spring. This is a very elegant solution due to its simplicity, and also due to its good aesthetics.
  • the impact absorber can be provided with recesses or through openings for the passage of fixing elements and/or structural components.
  • the front end of the impact absorber is above the wheel such that the suspension means transmit the impacts to the platform through a region located just above the front wheel, the support of the front wheel bearing preferably on a lower surface of the impact absorber.
  • the scooter comprises steering means and a link between the support and the steering means.
  • the steering can be implemented in a classical manner by means of a steering rod, although of variable length, for example by means of a telescopic coupling.
  • a steering rod for example by means of a telescopic coupling.
  • Another way of implementing the steering is by means of an electric steering motor, arranged to drive the front wheel support, the rotation of this motor being controlled from the handlebar.
  • Another option is to use cables, either provided with forwarding or by using the well-known Bowden cables.
  • the impact absorber extends backwards by means of a rear end, a rear wheel bearing on the rear end of the elongated element such that the impact absorber also constitutes the suspension of the rear wheel.
  • the steering means comprise a steering rod that can rotate with respect to the platform, the support passes through the impact absorber, such that the link between the support and the steering rod is placed over the impact absorber.
  • the link between the support and the steering rod is mechanical and is telescopic such they are mutually linked according to a single degree of freedom.
  • the platform has an upper prolongation that extends forwards and upwards, such that it encloses an upper portion of the steering rod, the link between the support and the steering rod being preferably inside the upper prolongation.
  • This upper prolongation can also serve as a cable concealment element when this is the option for the scooter's steering system.
  • an articulation portion of the support located above the impact absorber and below the link between the support and the steering rod is articulated or is elastic such a that it allows bending the articulation portion in the plane defined by the steering rod and the longitudinal direction of the scooter.
  • the articulation portion comprises a cardan articulation and/or elastic portion such that is bendable.
  • the impact absorber is attached to the platform in a central area of the platform, the central area being preferably located in the second third of the platform.
  • a very advantageous effect of the invention is that the suspension means can be extended throughout virtually the entire scooter. That offers many possibilities for anchoring and joining, and also many possibilities for damping. For example, when anchoring or joining the impact absorber in a central area of the scooter, which could be for example an area that extends a considerable portion of the scooter, such as 20% of its total length, will achieve a very comfortable dynamics for the user, because the impact forces can be distributed much more than in the known scooters, where all the impacts are concentrated in the front area.
  • the scooter comprises a rotating bearing for transmitting the forces between the support of the front wheel and the impact absorber.
  • the attachment between the platform and the elongated impact absorber comprises elastic parts, and is preferably formed by a transversal axis that allows the impact absorber to rotate with respect to the platform, and at least four pairs of elastic parts, preferably cylindrical or triangular, that elastically limit the rotation angle of the impact absorber with respect to the platform around said axis.
  • the impact absorber when subjected to certain impacts, the impact absorber can be rotated instead of be deformed, decreasing the stress to which the impact absorber is subjected.
  • the impact absorber(s) is (are) made of plastic, metal, fiber material, carbon fiber, composite or wood.
  • the impact absorber can be made of a broad range of materials and at the same time can have a broad range of geometries, while achieving the desired impact absorption.
  • the scooter comprises a retractable handle in the rear portion or stern of the platform.
  • a known solution for having a scooter carrying handle is to provide a through opening in the platform.
  • this solution is expensive, and implies weakening of the user platform, which is an important sacrifice when it comes to a purely auxiliary element.
  • the retractable handle arranged in the stern of the scooter in an area less structurally compromised, is very advantageous, since it does not affect the structure, it is easy to implement, and is hidden and symmetrical.
  • the scooter V comprises a user support platform 1, a front wheel W and a support 3 of the front wheel W.
  • the scooter is provided with suspension means which comprise an impact absorber 4 linked to the platform 1.
  • the impact absorber 4 is a key component of the present invention, which main concept is based in making it independent of the steering means by allowing it only to move in the median plane MP. That is, the impact absorber of the invention does not rotate with the front wheel. This is achieved by providing an impact absorber 4 comprising a front end 41, the impact absorber 4 being movable or deformable only in a median plane of the platform 1 such that the support 3 of the front wheel W is rotatable with respect to the impact absorber 4 to allow steering of the scooter, the support 3 of the front wheel W leaning on the front end 41 of the impact absorber 4, such that the suspension means S transmit the impacts to the platform.
  • the front end 41 of the impact absorber 4 is above the wheel W such that the suspension means S transmit the impacts to the platform through a region located just above the front wheel W, the support 3 of the front wheel W bearing on a lower surface 42 of the impact absorber 4.
  • This leaf spring can consist, as mentioned, in two half-bodies that join in the bow 41, or front end.
  • the impact absorber is a leaf spring 4 like a unitary platform, that is to say in one piece, although provided with the necessary openings for the passage of joining elements between the lower platform elements BAT, where the battery could be housed, and the upper platform elements B1, where the user leans.
  • the scooter comprises steering means 2 and a link 23 between the support 3 and the steering means 2, the steering means 2 comprising preferably a steering rod 2 that can rotate with respect to the platform 1.
  • the support 3 passes through the impact absorber 4, such that the link 23 between the support 3 and the steering rod 2 is placed over the impact absorber 4.
  • the link 23 between the support 3 and the steering rod 2 is mechanical and is telescopic (not shown) such they are mutually linked according to a single degree of freedom. Therefore, when an impact occurs and the support 3 moves upwards, its upper end moves axially inside a steering rod 2, which is integral with the steering handlebar Ha. This is the only degree of freedom allowed, as they cannot rotate relative to each other to ensure steering ability.
  • the impact absorber 4 extends backwards by means of a rear end 43, a rear wheel W2 bearing on the rear end 43 of the elongated element 4, such that the impact absorber 4 also constitutes the suspension of the rear wheel W2.
  • the impact absorber has a shape comprising two inflexion points.
  • the platform 1 has an upper prolongation 11 that extends forwards and upwards, such that it encloses an upper portion 21 of the steering rod 2, the link 23 between the support 3 and the steering rod 2 being preferably inside the upper prolongation 11.
  • This upper prolongation 11 is a novelty in itself when applied to a scooter V.
  • the invention allows the steering bar 2 to be smaller in size, which in turn allows said upper prolongation 11, which is integral with platform 1, also to be slender.
  • it allows hiding steering elements, such as in this case the steering bar 2, or in other cases it could hide steering control cables CB (as those shown in Figures 17 to 19 ), Bowden type, electrical cables, or any auxiliary technical element. Therefore, it is not necessary that the purely technical elements have perfect finishes, since the upper prolongation 11 already performs the aesthetic function.
  • an articulation portion 31 of the support 3 located above the impact absorber 4 and below the link 23 between the support 3 and the steering rod 2 is articulated or is elastic such a that it allows bending the articulation portion 31 in the plane defined by the steering rod and the longitudinal direction of the scooter V.
  • This articulation portion 31 can comprise a cardan articulation and/or elastic portion 31 such that is bendable.
  • Figure 15 shows that a portion of the front wheel support 3 is bendable.
  • the part that can be folded 31 is part of the support 3. That has been done so, because between said part 31 and the wheel support there are no axial movements, as there are between the upper end of 31 and the steering bar 2, because to allow the absorption of the displacements caused by the impacts or by the bending of the steering column, it is necessary that there be, as it has been connected, a telescopic link.
  • the scooter comprises a rotating bearing 34 for transmitting the forces between the support 3 of the front wheel W and the impact absorber 4.
  • FIGS 5, 6a and 6b illustrate one of the advantageous effects of the invention.
  • the invention allows the damping function to be carried towards the platform, including the union between impact absorber 4 and platform 1. This allows to create kinematics such as the one illustrated in the mentioned figures.
  • a ⁇ 2 articulation axis is highlighted. This axis ⁇ 2 allows the relative movements illustrated in Figures 6a and 6b .
  • This axis illustrates roughly a kinematics sought between components 1 and 4. It can be implemented in many ways. For example with a physical axis that matches the axis ⁇ 2. Another way of implementing it, which allows the joint area to be distributed in space, to distribute forces (and to reduce the requirements in terms of materials) is as illustrated in Figures 7 to 10 , using elastic elements K.
  • the scooter preferably comprises, in an ascending slope section, a retractable handle H.
  • the rear handle H of the platform is articulated with the platform by means of the axis ⁇ H, transverse to the scooter.
  • a housing H1 is provided to hide the handle H.
  • an actuator or HB button can be provided that allows, by push, to release the handle so that it goes out to its use position.
  • a scooter V comprising a user platform 1, provided with an upper part B1, a rear end of said upper part B1 being provided with a housing H1, a rotating handle H articulated with said upper part B1 by means of a ⁇ H axis, so that the handle H can be moved between a position of use in which it is outside the housing H1, and another hidden position in which its upper part is flush with the upper surface of the upper part B1 of the platform 1.
  • a push-type release button HB can be provided that allows the handle H to be released, which can be deployed outwardly driven by a spring (not shown).
  • Figure 16 shows an embodiment in which a steering rod 2 is dispensed with.
  • the steering components consist of an electric motor, in turn constituted by a stator S3 and a complementary rotor R3 that can rotate moved by stator S3.
  • the impact absorber 4 has a shape and structure that allows to accommodate such a steering element.
  • the handle has a user interface that allows it to remotely steer the wheel, which can rotate around the ⁇ R axis.
  • said user interface emulates a mechanical steering rod, for example it comprises movement sensors (e.g. accelerometers or gyroscopes) in a handle or a rod which can rotate but which does not mechanically transfer a steering movement to the front wheel W, instead the rotation is transferred electronically.
  • movement sensors e.g. accelerometers or gyroscopes
  • the steering means comprise Bowden CB cables. These are implemented, in a known manner by means of support bushes 72, a sheath 73 inside which is the traction cable. As can be seen, through an opening 74, a large part of the cable 75 can be hidden inside the upper extension 11.
  • the system is completed with an actuating crown 71, which acts as a lever between the ends of the two cables. It is a system known in the handling of boats, but which constitutes a novelty according to the present invention. And it stands out that what makes it especially easy to integrate a steering solution based on a rotary cable-operated support is the structure based on an impact absorber 4 that can only be moved in the mid-plane MP, as claimed.
  • FIG. 19 The operation of a cable-based steering system is shown in simplified form in Figure 19 .
  • the handlebar Ha is shown on the right, which has two associated pulley portions PH, where the ends of the CB drive cables are anchored.
  • the radii of PH and the crown will be identical.
